Hop twin finder
Pick a hop. See its 8-axis flavor profile, the most similar varieties by quantitative analysis, and the brewer-curated substitutes. Compare any two hops side-by-side.
Flavor compass 8 axes
Hop detail
Algorithm matches By flavor similarity
Calculated by cosine similarity over the 8 flavor axes — hops whose radar shape most closely matches the selected one.
Official substitutes Brewer-curated
The substitute hops listed by brewers and hop suppliers as functional replacements for this variety.

How this works
Flavor axes. Every hop's flavor notes from hops.json are mapped to one of 8 categories: Citrus, Tropical, Stone & Berry, Pine & Dank, Herbal & Tea, Floral, Spice & Earth, Wine & Funk. The first listed note is weighted heaviest (it's the dominant character); later notes contribute less. The result is a profile vector across all 8 axes.
Similarity. The "algorithm matches" panel uses cosine similarity between profile vectors. Two hops with the same shape but different intensities still match — the algorithm cares about which axes dominate, not absolute scoring.
Substitutes. The "official substitutes" panel comes from each hop's substitutes field in our data — the conventional list that brewers and hop suppliers recommend. Sometimes these agree with the algorithm; sometimes they don't, which often surfaces an interesting flavor twin you wouldn't have thought of.
